Having your ISP suddenly cut off service or your home router fail is always a surprise, especially if you were planning a movie night. Fortunately, modern technology allows you to quickly solve the problem of a lack of network by using your smartphone as a mobile router. Internet Sharing via the built-in Wi-Fi module - this is a standard function available to owners of most gadgets based on Android and iOS.
For smart TV owners LG Smart TV This method becomes a real salvation, allowing you to continue streaming content through apps. YouTube, Netflix or IVi Without lag. The setup process doesn't require in-depth technical knowledge, but it does have its own nuances related to frequency band compatibility and power consumption. In this article, we'll cover in detail how to turn your phone into a hotspot and properly connect it to your TV.
Before we get into the practical steps, it's worth mentioning that connection quality directly depends on the strength of your cellular network signal and your carrier's data plan. Unlimited plans often have tethering restrictions, so be sure to check your contract terms to avoid speed limits. Now let's look at a step-by-step algorithm of actions for different use cases.
Preparing your smartphone for modem mode
The first step is to properly configure your mobile device, which will act as the signal source. Operating system interfaces may differ, but the steps are the same for most models. You need to activate the personal hotspot feature by hiding or revealing the network name.
On devices running Android The way to do this is usually through the settings menu. Go to "Connections" or "Network & Internet," then select "Wi-Fi Hotspot" (or "Tethering & Portable Hotspot"). It's important not only to turn on the switch but also to configure security settings to prevent unauthorized access to your network.
- 📱 Create a complex password consisting of letters and numbers to prevent your neighbors from using your data.
- 📡 Select the 2.4 GHz frequency range if your LG TV is an older model and does not see the 5 GHz network.
- 🔋 Turn off power saving mode on your phone to prevent it from dropping the connection while you're browsing.
To the owners iPhone You should also pay close attention to your settings. In the Personal Hotspot menu, you need to allow other devices to connect. Note that iOS may require connection confirmation for each new device the first time you pair it. Make sure cellular data is enabled and the network signal is stable.
⚠️ Attention: When actively using Wi-Fi, your smartphone may become very hot and drain quickly. It's recommended to keep the device connected to a charger or remove its case for better cooling.
Once the hotspot is activated, the network name and password will be displayed on your phone's screen. You'll need this information in the next step when setting up the TV itself. Keep your smartphone's screen turned off completely to monitor the connection status.
Algorithm for connecting LG Smart TV to an access point
Now let's move on to the TV itself. The operating system interface webOS, which is installed on most modern LG models, is convenient and logical. You will need a remote control Magic Remote or a standard remote control to navigate the menu.
Press the "Settings" button (the gear icon) on the remote to open the main menu. Go to the "All Settings" section (the three dots at the bottom of the screen or the corresponding icon). We're interested in the "Network" section, which contains all internet connection settings.
Select "Wi-Fi Connection." The TV will automatically scan for available networks within range. In the list that appears, find the network name (SSID) you set on your smartphone. If the network is hidden, select "Add hidden network" and enter the name manually.
☑️ Check before connection
After selecting the network, the TV will ask for a password. Enter it carefully using the on-screen keyboard. Please pay attention to case sensitivity, as the system is case-sensitive. Once entered, click "Connect."
If everything is set correctly, a green icon or the word "Connected" will appear next to the network name. The system may prompt you to update the software or adjust the time. Accept these, as the apps require the current date for proper operation.
Frequency range settings and compatibility
One of the most common issues when connecting a TV to a phone is frequency incompatibility. Modern smartphones often default to the 5 GHz band, which offers high speeds but has a shorter range and isn't supported by all devices.
Old TV models LG (manufactured before 2015-2016) may simply not detect the 5 GHz network. In this case, you need to force the phone's access point to switch to 2.4 GHz mode. This can be done in the access point's advanced settings.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range | High (up to 50 m) | Medium (up to 20 m) |
| Penetration of walls | Good | Low |
| Compatibility with LG TV | 100% (all models) | Only new models |
To switch the range to Android Go to the access point settings, find the “AP Band” or “Frequency Range” item and select “2.4 GHz”. iOS Switching occurs automatically if the connected device does not support 5 GHz, but sometimes you need to disable the "Maximum Compatibility" feature in the settings if problems occur.
It's also worth considering the number of connected devices. If you have many devices connected to your phone, the TV's bandwidth may drop, leading to buffering of high-definition video.
Solving DNS issues and access restrictions
Sometimes the TV shows "Connected" but the internet isn't working. This is often due to DNS server issues or blocking by your service provider. In such cases, manually configuring your network settings can help.
In the network settings menu on your LG TV, select your Wi-Fi network and click "Additional settings" or "Advanced Wi-Fi settings." Uncheck "Automatic" (for IP or DNS) and enter the data manually. The most universal solution is to use public DNS from Google or Cloudflare.
- 🌐 DNS server 1:
8.8.8.8(Google) - 🌐 DNS server 2:
1.1.1.1(Cloudflare) - 🔧 IP address: leave it automatic if there are no network conflicts.
Another reason for unavailable internet access may be that your carrier is blocking tethering. Some providers detect that the traffic is coming from another device than your phone (based on the packet TTL) and limit the speed or block the connection.
⚠️ Attention: Bypassing operator restrictions by changing the TTL may violate the terms of the user agreement. Use such methods only for personal use and after familiarizing yourself with the terms of your plan.
To check if the settings are working, launch the built-in browser on the TV or try opening the app YouTubeIf the video starts loading, the issue is resolved. If not, try restarting both devices.
Using a USB modem as an alternative to Wi-Fi
If your wireless connection is unstable or your TV can't connect to the hotspot for some reason, consider a wired USB connection. This method often provides a more stable ping and doesn't drain your phone's battery as quickly.
To implement this method, you'll need a USB cable (usually USB-A on one end and USB-C or Lightning on the other) and a smartphone that supports USB tethering. Connect the phone with the cable to the USB port on your LG TV.
On your phone, in the hotspot and modem settings, turn on the "USB tethering" switch. The TV should automatically detect the wired connection and switch to it. In the network menu, the status will change to "Wired connection" or "USB Ethernet."
Why is a USB modem better than Wi-Fi?
A wired USB connection ensures stable data transfer without interference from microwaves and neighboring routers. Additionally, the phone can be charged (albeit slowly) from the TV in this mode, extending battery life.
The advantage of this method is the absence of lag, which is critical for online gaming or viewing 4K content. However, not all LG TV models support drivers for all smartphone types, so compatibility should be tested experimentally.
Optimize traffic and save battery
Since you use mobile data, it's important to monitor your data usage. Streaming services consume a huge amount of data, especially in high definition. Adjusting the video quality will help prevent unexpected data exhaustion.
In applications on the TV (for example, YouTube or Kinopoisk) You can manually set the playback quality. Instead of "Auto," select 720p or 1080p. The difference may not be as noticeable on a large screen when watching from the couch, and your data usage will be significantly lower.
It's also a good idea to disable automatic app and system updates on your TV while using a mobile network. These processes can silently eat up several gigabytes of storage in the background.
Remember to turn off your phone's hotspot after you finish viewing content. This will not only save battery life but also protect your data from potential unauthorized access attempts if you forget to set a password.
Frequently Asked Questions (FAQ)
Why can't my LG TV see my phone's hotspot?
The issue is most likely related to the frequency range. Try switching your phone's access point to 2.4 GHz mode. Also, make sure your phone's data connection is enabled and you're not too far from the TV.
Is it possible to share the Internet via Bluetooth?
Technically, this is possible (Bluetooth PAN), but the data transfer rate via Bluetooth is extremely low (no more than 2-3 Mbps). This is only enough to load simple web pages, but the video will constantly stop. Wi-Fi or USB is recommended.
Does the phone get very hot when operating in router mode?
Yes, the Wi-Fi module operates under high load when constantly transmitting data. The phone may become noticeably warm. We recommend removing the case and placing the device on a hard surface to dissipate heat, or connecting it to a charger.
Does Android or iOS version affect speed?
The OS version itself has little impact; hardware support for Wi-Fi standards (802.11n, ac, ax) and cellular signal strength are more important. However, older versions of Android may have access point bugs that are fixed with a system update.
